Key result
Mean plasma BNP levels were significantly higher in patients with congestive heart failure compared to those without (483.1 vs 79.2 pg/mL; p=0.005) and correlated positively with LVEDP.
Why the study?
Does plasma BNP level correlate with the presence of congestive heart failure and left ventricular end diastolic pressure in patients undergoing hemodynamic monitoring?
Population
50 patients admitted for treatment and hemodynamic monitoring (34 with congestive heart failure, 16 without)
Comparison
B-type natriuretic peptide measurement and… vs Patients without congestive heart failure
Design
Cross-sectional

May support BNP for HF hemodynamic assessment; leaves open prospective validation before clinical adoption.
Observational (n=50)
Does plasma BNP level correlate with the presence of congestive heart failure and left ventricular end diastolic pressure in patients undergoing hemodynamic monitoring?
Absolute Event Rate: 483.1% vs 79.2%
p-value: p=0.005
Plasma BNP is significantly elevated in patients with congestive heart failure and correlates positively with left ventricular end-diastolic pressure, supporting its utility in hemodynamic assessment.
Kwon et al. (2003) conducted an observational in Congestive Heart Failure (n=50). Congestive heart failure vs. No congestive heart failure was evaluated on Mean BNP level (p=0.005). Mean plasma BNP levels were significantly higher in patients with congestive heart failure compared to those without (483.1 vs 79.2 pg/mL; p=0.005) and correlated positively with LVEDP.
